چکیده انگلیسی
The hollow-core photonic crystal fiber (PCF) is filled by highly nonlinear liquid chloroform (CHCl3) in the center core. The CHCl3-filled PCF with an appropriate geometric parameters exhibits a normal dispersion profile in the visible-to-near-infrared (NIR) region, where the values of group velocity dispersion (GVD) in the vicinity of 1060-nm pump wavelength can be tuned in the range from â20 to â50Â ps/nm/km. Furthermore, the nonlinear parameters at wavelengths <1100Â nm are higher than 0.7Â Wâ1Â mâ1, which can lead to a significant enhancement of the spectral broadening, especially on the blue side. The numerical results show that, when 100-fs pulses centered at 1060Â nm are launched in the 0.01Â m-long fiber (47Â kW peak power), the generated supercontinuum (SC) spectra with high degree of coherence can cover near 2 octaves spanning from 340 to 1360Â nm at â20Â dB level. The spectral variations are < 5Â dB in the wavelength range of 365-1315Â nm.
